摘要
采用高频红外吸收法测定延迟石油焦中的硫含量,对坩埚、助熔剂、称样量、冲洗时间、截止电平等测定条件进行了优化研究,该方法快速、简便,具有良好的精密度和准确度。
The sulfur content in petroleum coke was tested by high frequency infrared absorption method. The determination condition parameters such as the crucible, flux, washing time, the sample amount and cut-off level were optimized. The tested results showed that the method is rapid and simple with good precision and accuracy.
